Question

1. If f(x)= 2x^3 + x^2 +3
a) How many turning points does the graph of f(x0 have?
b) fin f(x) using any method.
c) find the abscissa (x-value) of every turning point of f(x)
d) what is the slope of tangent to f(x)= 2x^3 - x^2 + 3, when X=2
e) find the equation of the tangent line at the point where x=2
someone please help me.
